[Pages:1]DIFFERENTIAL PRESSURE PILOT 1356

Differential Pressure Pilot 1356

DESCRIPTION

MODEL 1356 DIFFERENTIAL PRESSURE lNormally closed, increasing differential pressure opens. lMultiple spring ranges for accurate control. lCan be local or remote sensed. lSimple adjustment. lAll parts replaceable while mounted on valve. lRubber to metal seat for positive shut-off. lBronze or stainless steel construction.

The Model 1356 is a two-way, normally closed pilot, that senses high pressure under its diaphragm, low pressure above the diaphragm, and balances the differential pressure against an adjustable spring load. An increase in differential above

the spring set point tends to make the pilot open.

The Model 1356 is the standard pilot for OCV Series 110 Differential Control Valve. Sensing high and low pressures and opening at the differential set point, the pilot modulates the main valve to maintain the required differential pressure.
